indicated that in 0 days moisture content of shrimp was 77.6%, in 7
days it increased to 81.3% and after 14 days the moisture was
increased to 83.5%. The increase of moisture was similar to present
study over the range of time. At 24th hours prawn was without frozen
prawn is near unacceptable.
prawn muscle decreased considerably with storage period. A slight
decrease in crude protein with the laps of storage period was entirely
due to the formation of free drip accompanied by loss of some
sarcoplasmic protein. Peplow et al. indicated that in 0 days protein
content of shrimp was 19.6%, in 7 days it was increased to 16.5% and
after 14 days it was increased to 14.7%. The author found certain
difference but the decrease of protein happened similarly. The initial
lipid content of fresh prawn was slightly increased to 1.42×10⁴ cfu/g
respectively. Shrimp collected from Bagerhat, Khulna, and Satkhira
and from all the points (Gher, Depot, Agent, and Processing Plant)
indicated value within 10.5cfu/g, which was within the acceptable limit.
De Silva reported that there was a gradual loss in quality of shrimp as
stored at four different temperatures (0°C, 10°C, 20°C and 30°C). The
highest spoilage rate was observed in shrimp stored at 30°C. The APC
of freshly harvested Gulf of Maine shrimp ranged from <100 to 1.6×10₂
cfu/g. These data are comparatively lower than data reported on
shrimp harvested in other areas of the United States. In Gulf of Mexico
shrimp, Green reported APC of 4.2×10⁴ cfu/g and Vanderzant et al.
found APC of 2.1×10⁵ cfu/g. Harrison and Lee reported on Pacific
shrimp and found APC ranging from 3×10⁵ cfu to 1.3×10⁶ cfu/g. Iced
shrimp as purchased. by the firm had a plate count of 4.8×10⁶ cfu/g.
The author’s present the result in fresh condition is similar to that result
though there is some dissimilarity in frozen condition. Total bacterial
load (Aerobic Plate Count) of raw freshwater prawn was 4.37 × 10⁵
cfu/g whereas in frozen freshwater prawn was 1.42 ×10⁵ cfu/g was
reported by Khan et al. Present study showed similar result.
Detection of unwanted chemical in prawn
(Macrobrachiumrosenbergii): The concentration of Cd, Cu, Mn, Zn
and Pb were 0.179µg/g, 0.517µg/g, 6.935µg/g, 11.288µg/g and
